Telkom is a ****

Last year October i was offered a router and 80 gb of data which I will pay R240 each month but in two months time the amount escalated to R513 without any agreement of mine .I called and they said it is subscriptions I might have clicked online.I advised that I did not agree to anything and would like to stick to the amount agreed on contract. I then played for December and January but my simcard was still blocked and I could not use and they said they will not open it until I pay for the amount that was not on agreement.Since I was not paying for a service which I was not getting I then stopped making payments altogether. Now the account is still escalating but i have not used the data nor router in a year.Telkom is debiting more than R1800 from my account which I despute monthly using different codes to access my bank.Now i will not pay for service I'm not getting and at that I will not be paying nothing above my agreement.I want Telkom to stop debiting from my bank account because its annoying to always go to the bank and reverse their transactions. If anyone wants to take a contract let it not be with Telkom their service is sloppy they don't answer calls nor reply to emails all they will do is get into your bank and chow your money period.
